I think hacking the source is overkill.

Your locking problem can be solved by running diff with the -n option
(proceed without lock).

Do you want to see the diff output to assist in typing the "this is
what I did" message? If not, consider using the loginfo file. I think
the commitinfo or editinfo files can help if you want it in the editor
window, but I haven't done this personally.
